The person who built a lot of them cursed the circuit like the day they were born, and like Devi at the time, wouldn't build another for pretty much any price.

It's simple as described but the consistency of stuff from that era was...not exactly there.

I went through two builders before finding one who could actually do one in any stretch of the way.

One thing on the DIY stuff relating to the TP: which version of the SM etc do you use (versus what's in it), do you include the chaos and noise switches not present in the real one , etc?

We went down a weird hybrid road plus the starve on my second - it doesn't make *any* sound on some settings, some knobs don't do squat in some settings, etc. We added things pretty much because we could. It's superior to the original TP by a long shot but loses the faux choppy trem weirdness clicking that the original has in the mods (but becomes far more of an oscillating synth/weird sputter pedal while simultaneously being able to do more standard fuzz stuff.

I've had the Test Pattern from Hell for 8-9 months now, and I'm still finding new stuff in it. It took me a good 2 years to get consistent with the original, and it still can pull something out that surprises me from time to time.

He says:

"To get 'closer' to the original test pattern version of crazy, putting the 'high gain' versions of the active components and also lowering the R1 value will put it back squarely in the original TP area." Or removing R1 completely if you want maximum insanity.

Go with higher-gain versions of things as well to get more silliness/uncontrollable stuff if you so desire as well.

Effectively, this version is a "more refined" and controllable (not saying much) Test Pattern with a hybrid of design choices from the various Devi circuits - if I recall, it's the originalish Soda Meiser versus the last (then) revised that's in the stock one, with noise and chaos switches plus the normal bypass half the circuit one, and add a starve.

Have a PDF of a brew your own PCB as well if anyone needs it.

maybe more octavia than tone machine
the octave down is good two
tons of splattery stuff from this thing

the case is ridiculously stupid
if you can ignore the aesthetics it is a beast
